Most investors know about putting a fixed amount into the market every month. But there is a less common strategy that takes a more dynamic approach: value averaging.
Understanding what value averaging means and how it works can help you decide whether it fits your investment style and goals.
What Is Value Averaging?
Value averaging is an investment strategy where you adjust how much you invest each period based on how your portfolio is performing, rather than contributing a fixed amount every time.
The goal is to keep your portfolio growing toward a predetermined target value on a set schedule. If your portfolio has grown less than expected, you invest more to make up the difference. If it has grown more than expected, you invest less or even sell a portion.
For example:
- Your target is for your portfolio to grow by $500 every month.
- In month one, you invest $500 and the portfolio reaches $500.
- In month two, the market drops and your portfolio falls to $400. You invest $600 to bring it back to the $1,000 target.
- In month three, the market rises and your portfolio reaches $1,200. You invest only $300 to reach the $1,500 target.
The contribution changes each period based on what the portfolio needs, not on a fixed schedule.
Value averaging was developed by economist Michael Edleson in the 1980s and later popularized through his book on the subject.
Advantages and Disadvantages
Like any investment strategy, value averaging has genuine strengths and real tradeoffs worth understanding before applying it.
Advantages
Naturally buys more when prices are low. Because you contribute more when your portfolio underperforms, you are effectively buying more shares when prices are depressed. This can lower your average cost per share over time.
Enforces discipline. The strategy gives you a clear rule to follow each period. Rather than guessing how much to invest based on market conditions or emotion, you follow the target formula.
Can improve long-term returns. Studies comparing value averaging to dollar cost averaging have suggested that value averaging can produce slightly better average purchase prices over long periods, though the difference depends heavily on market conditions.
Disadvantages
Requires more cash on hand. When markets underperform, you need to invest significantly more than usual. This requires maintaining a cash reserve specifically for this purpose, which may reduce the capital available for investment.
Can require selling in rising markets. If your portfolio grows well above target, the strategy may require you to sell holdings. This creates potential tax events and goes against the instinct of many long-term investors to hold winning positions.
More complex to manage. Unlike a simple fixed contribution, value averaging requires you to calculate the required contribution each period based on portfolio performance. This adds administrative effort and the potential for errors.
Emotionally harder to follow. Contributing a much larger amount during market downturns, exactly when confidence is lowest, can be psychologically difficult even though it is mathematically the right move.
How Value Averaging Differs from DCA
Dollar cost averaging (DCA) and value averaging are both systematic investing strategies, but they work in fundamentally different ways.
With DCA, you invest a fixed dollar amount at regular intervals regardless of market conditions. The simplicity is the point. You do not need to calculate anything or make decisions based on portfolio performance.
With value averaging, the amount you invest changes every period based on how far your portfolio is from its target value. The strategy is more responsive to market behavior but also more demanding to execute.
| Value Averaging | Dollar Cost Averaging | |
|---|---|---|
| Contribution amount | Variable, based on portfolio performance | Fixed every period |
| When markets fall | Invest more | Invest the same |
| When markets rise | Invest less or sell | Invest the same |
| Complexity | Higher | Lower |
| Cash reserve needed | Yes | Not necessarily |
| Best for | Active, disciplined investors | Hands-off, consistent investors |
Both strategies aim to reduce the impact of market timing on your returns. Value averaging does this more aggressively but at the cost of simplicity.
When Value Averaging Works Best
Value averaging is not a one-size-fits-all strategy. It tends to work best in specific circumstances.
Volatile markets
Because value averaging automatically increases contributions when prices fall, it is particularly effective in markets that experience significant swings. The more volatile the asset, the more the strategy can benefit from buying at lower prices during downturns.
Long time horizons
The advantages of value averaging compound over time. Investors with decades ahead of them have more opportunity to benefit from the lower average purchase prices the strategy can produce. Understanding your investment time horizon before choosing a strategy is key, since over shorter periods the difference between value averaging and DCA narrows considerably.
Investors with flexible cash flow
Value averaging requires the ability to invest variable amounts each period, sometimes significantly more than planned. Investors with stable income, a dedicated cash reserve, and no pressing financial obligations are best positioned to follow the strategy consistently without being forced to deviate.
When you want a more active approach
Value averaging suits investors who want a systematic strategy but also want their contributions to respond to market conditions. It is a middle ground between passive fixed contributions and active market timing. For those who prefer a fully passive alternative, a buy-and-hold approach may be a better fit.
Practical Example of Value Averaging
Here is a simple three-month example to show how value averaging works in practice.
Your target: portfolio grows by $1,000 per month.
Month 1 Target portfolio value: $1,000. Portfolio performance: neutral. Contribution: $1,000.
Month 2 Target portfolio value: $2,000. Market drops sharply, portfolio falls to $1,400. Contribution needed: $600.
Month 3 Target portfolio value: $3,000. Market rallies strongly, portfolio rises to $2,800. Contribution needed: $200.
Over three months, total contributions were $1,000 + $600 + $200 = $1,800, compared to $3,000 under a fixed DCA approach. The lower total contribution was possible because market gains did some of the work. In a down market scenario, the reverse would apply and contributions would be higher.
Conclusion
Value averaging is a disciplined, systematic strategy that adjusts your investment contributions based on portfolio performance rather than a fixed schedule. It naturally buys more when prices are low and less when prices are high, which can improve average purchase prices over time.
However, the value averaging strategy demands more from investors: more cash flexibility, more calculation, and more emotional discipline during downturns. It works best for investors with long time horizons, flexible cash flow, and a willingness to engage actively with their contribution schedule.
For those who find the complexity manageable, it can be a powerful complement or alternative to simpler approaches like DCA. Pairing it with a well-structured portfolio rebalancing plan ensures your overall allocation stays on track as contributions vary from month to month.
FAQ
What does value averaging mean?
Value averaging is an investment strategy where you adjust your contribution each period to keep your portfolio growing toward a fixed target, investing more when returns fall short and less when returns exceed the target.
What is the main difference between value averaging and dollar cost averaging?
DCA uses a fixed contribution every period. Value averaging uses a variable contribution based on portfolio performance, buying more when prices are low and less when prices are high.
Is value averaging better than dollar cost averaging?
Not necessarily. Value averaging can produce better average purchase prices in volatile markets, but it requires more cash flexibility and discipline. DCA is simpler and more practical for most investors.
